🛠 MiniMax H3 Ecosystem: Community Roundup #13

The 'Neuronaut' channel has compiled the 13th part of #minimaxH3 — open-source ComfyUI nodes for the MiniMax H3 video model that have appeared in a month and a half.

🌍 Following the example of Wan and Flux, H3 is being surrounded by infrastructure: Contex-Loop (367 stars) stitches scenes so that motion and sound continue across seams — the author's goal; MultiRef (165) extends clips with references; Multishot-Advance caches shots; Qwen3.8-27B writes prompts offline based on H3 Skills; there is a package for 8 GB VRAM.

👤 ComfyUI users have access to long and multi-shot video pipelines, laptop owners with 8 GB VRAM can run H3, and the LoRA Polyhedron improves skin, hands, and eyes via triggers (the author recommends a low weight).
